🇳🇬 Sandcrete block construction

Nigeria Building Cost & Bill of Quantities Generator

A real, stage-by-stage BOQ for sandcrete block construction — export just the stage you're funding right now.

Nigerian house building is almost always funded in stages — foundation this year, blockwork next, roofing when funds allow — which is exactly why a single 'total project cost' number is often the least useful thing a calculator can hand you. This generator's category structure follows Nigeria's own real stage-billing convention directly (Stage 1 Preliminaries through Stage 8 External Works & Services), and you can export just the stage you're currently funding rather than the whole project at once.

The quantities themselves are built on real, verified coefficients, not a rounded 'concrete block' guess: roughly 10 sandcrete blocks per square metre of wall and 1 bag of cement per 35 blocks at 9-inch thickness, cross-checked against a live Nigerian block calculator. Cement and iron-rod prices here move fast with exchange-rate swings, which is exactly why this tool hands you real quantities to lock in with suppliers early, not a naira figure that's already stale by the time you read it.

It also includes the real site-infrastructure items a generic BOQ tool built for a Western market leaves out entirely: a borehole for water supply and diesel generator provision for site power, both standard, budgeted line items on most Nigerian sites rather than an edge case — plus Boys' Quarters and compound fencing where your build includes them.

What's in a Nigeria BOQ from this generator

  • Stage 1 — Preliminaries and site setup, including borehole and generator provision
  • Stage 2 — Substructure: foundation concrete, columns and beams
  • Stage 3 — Superstructure: sandcrete block walls (9-inch external, 6-inch internal), real 10 blocks/m² coefficient
  • Cement bags at the real 1-bag-per-35-blocks (9-inch) ratio
  • Stage 4 — Roofing structure and covering
  • Doors and windows (room-count and area-based, so larger houses aren't undercounted)
  • Plumbing fixtures and rough-in, electrical points
  • Boys' Quarters and compound fencing (if selected)
  • Export just one stage at a time — the same document your bank or supplier expects for that stage's funding release

Nigeria Bill of Quantities — Frequently Asked Questions

Can I get a BOQ for just one construction stage, not the whole house?
Yes — since Nigerian house building is almost always funded stage by stage, this generator lets you export a line-item subtotal for just the stage you're currently working on (e.g. just Stage 3 blockwork), not only a full-project total.
What block size and cement ratio does this generator use for Nigeria?
9-inch (225mm) hollow sandcrete blocks for load-bearing external walls and 6-inch (150mm) blocks for internal partitions, at roughly 10 blocks per square metre of wall and 1 bag of cement per 35 blocks — cross-checked against a live Nigerian block calculator, not a generic 'concrete block' estimate.
Does this generator include a borehole and generator line for off-grid power and water?
Yes — unreliable grid power and water supply are a real, standard part of a Nigerian construction budget, not an edge case, so this generator's scope includes them by default rather than assuming stable utilities the way a generic Western BOQ tool would.
Does this generator include real Naira material and labor prices?
No — you get real quantities and price every line yourself. Cement and iron rod prices move quickly with exchange-rate swings, so a fixed national average would already be stale within weeks; pricing with your own current supplier quotes is the honest approach.
